To all whom it may concern:

Be it known that I Prune M. Gnpa'rr, a citizen of. the United states of America, residing at La Crosse, in the coun of Crosse and State of Wisconsin, ve 1nvented certain new and useful Improvements in Dial-Plate Constructions, of which the foliowing is a specification, reference being had therein to the accompanying drawin In t e construction of (gages for automobiles and of like in eating devices wherein a dial is confined in a casing an is swept by an index hand operated b mechanism contained within the casing, it is desirable that accew be had to the 1nterior and that the parts to be removed for obtainin such entrance thereto, be as few in 'num r and as ready of readjustment in ling again, as possrble.

This invention relates to a gage casing and to a disposition thereof whereby access can be had thereto readily through a construction which embodies very few parts which are quickly and readily assembled.

The invention consists in the matters hereinafter set forth, and are particularly pointed out in the appended claims.

In the drawings,

Figurelisatganviewindetailofadial plate used in e gage that embodies the invention; and

Fig.- 2 is a view, partially in elevation and partially in section, of a gage that embodies the invention.

As herein shown in preferred form, a casing 1 of suitable material contains any pressure or level indicating mechanism not shown herein, as the latter does not form per as apart of the invention. A suitable post 2 inthe casing which is detachably mounted on the bottom thereof in the usual manner or other like means, supports a dial plate 8. The latter has an u urned marginal flan 4 on the up r ge face of,which a ie'ld 5 of suits. le transparent material, as "glass, is clamped by means of an exterior collar 6 having an inturned annular flange 7.. The collar is in screwthreaded engagement with the casing and there may be a packing washer 8 mte d between the shield an 7 if esired.

As a consequence of this construction acmass is readily 'had to the gage by merely unreturns the flange I me mm mm Patented mar. is, 1919. Application fled m 10, m7. m1 Io. b80310.

screwin the collar and removinfi the shield which saves the dial plate fu y exposed and subject t 'withd-r-awal when the post that sup rte it isloosened as by any fastenmg mem rs which may connect the bottom of it with the casing. The remembling is likewise as quickly accomplished, as the usual casing rings between the dial plate and shield, .which are necessary in the ordinary construction to 've space for the pomtcr ordinarily emp oyed to travel bet een the shield and the dial plate, are

d lacking. It is to be noted that if the parts are proportioned as herein illustrated, the flange 4 is quite clear of the casing wall. Therefore, when the collar is brought against the dial, the latter yields sufficiently on its supports, which are way within the margins, so that the dial accommodates itself to any irr ari'ties of position or variations in thi ess of the parts, and there is a very close joint established between the shield and dial plate. Conseguentl the operator 'does not have to adust t parts and the whole structure to initial position and relation readily without great effort on the part of the assembler.

Obviously, changes in the details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is z- 1. ha gage, a casing, a dial-supportin means in the casing, a dial-plate secured on said means and sgrovided with an expansible flange, a ield resting on the outer face-edge of said fla e and a collar engaging over the casing a'p'ted to force the e 1e (1 against the ange and expand the same.

2. In a a casin a dial-supporting means in e casing, a ial-plate secured on said means provided with an upturned expansible flange, a shield resting on the outer edge-face of said flange and an adustabIe ool1ar en g over the casing End forcing the shiel into contact with the sage.

8. In a gage, erasing, a dial-supporting means in the casing, a dial plate secured on said means vided with an upturned expansible flange, a shield resting on the outer edge-face of mud flange and a screwthreaded collar engaging over the casing ing adapted to force the shield into contact 10 and forcing the shield into contact with the with the flange, and a. pm masher be- 'hmge. tween said 00 lar and said shi d.
